Recently, I’ve been working on creating Docker containers. Minimizing the image size is a topic of interest. A common pattern seems to be to ADD or COPY some data into the container, use it, and then delete it. This bloats the image. However, there’s a way to solve this!

I’m trying out vscode for editing, since it has a nice “file explorer” capability that I don’t get (at least by default) with GVim. However, the scrolling behaviour annoyed me. But I found a solution!

I’m very much a fan of black or at least plain backgrounds on my system; there’s much less clutter and distraction. When I upgraded my laptop to Ubuntu 20.04, I naturally configure my user session’s background to plain black. However, the login screen insisted on displaying some image rather than the plain black I wanted. Here’s how I fixed this.

I have an Ubuntu 16.04 server that runs the bip IRC proxy. Until recently, I was happily accessing bip from an Ubuntu 18.04 laptop. However, when I upgraded my laptop to Ubuntu 20.04, xchat refused to connect. This post describes how I fixed that.

The question of “why doesn’t sudo cd work?” has come up a couple times in the last few weeks. I figured that the explanation would make for an interesting blog post.
